THOMAS W. WADE, OF SPRINGFIELD, MISSOURI.

COOKER AND EVAPOBATOR.

Patented Nov. 10, 1908.

To all whom it ma concern:

Be it known that I, THOMAS W. WADE, a citizen of the United States,residing at Springfield, in the county of Greene and State of Missouri,have invented new and useful Improvements in Cookers and Evaporators, ofwhich the following is a specification.

, My invention relates to improvements in cookers and evaporators. Moreespecially to that class of evaporators and cookers which appliespressure of steam or li uid to the articles to be cooked, or evaporatel.

My invention consists in having a plurality of retorts separablyconnected with each other, and each separably connected with two waterreservoirs as hereinafter more specifically described and set forth inthe claim.

Figure 1, is a view in elevation of the entire device a part of thefurnace walls being cut away. Fig. 2, is a vertical cross section on theline r a of Fig. 1 showing a kettle suspended inside of the retort. Fig.3, is atop View of one of the retorts showing the cover fastenings.

Similar letters of reference indicate corresponding parts in the severalfigures".

A, represents an ordinary furnace made any desired size and shape whichreceives the frame work for the retorts S, S and B is a suppport and Bis a bridge wall in the furnace.

C is the grate-bar and D are the doors of the furnace.

F represents a blow -off pi e or water ipe connecting the retorts S, andS aid pipe is preferably placed below the retorts for completelycleaningthe same by opening the valve F on the outside of the furnace.

J is asteam pipe connecting all of the retorts and also the water gage Gwhich also connects with the lower water or blow off pipe F. The steampipe J at the outer end is also connected with the water tanks orreservoirs Q and Q by pipe P. This connecting pipe P is provided withsuitable cut off valves 0 so that water can be taken from either tank.

Surplus steam can be connected through the steam pipes K and P to tank Qand steam can be connected from one of the retorts into another by meansof this same connection of the pipe K with the different retorts. One ofthe tanks of water can be ke t cool for cooling either of the retortsfor ciianging its contents and the other tank ke t hot by the surplussteam from the retorts or supplying either of the retorts with hot waterwhen desired to reheat the retort taking hot water instead of cold intothe retort, thus saving steam, heat, time and fuel in reheating one ofthe retorts and also in taking extra water from the hot tank instead ofthe cold.

L'represents a safety valve and L a steam gage on each of the retorts.

L a thermometer for determining the heat or ressure of .the contents ofthe retorts.

is a steam tight cover for each of the retorts. It is provided with asuitable gasket M Said cover is secured firmly and quickly in positionby means of a setscrew and lever N which turns down on the handles N;for this purpose a washer may be used on the handles. Other means ofsecuring the cover or steam tight lids may be used but I prefer the onejust described. This steam tight cover is used when we cook or processvegetables or other things in the retort.

The can containing 'the vegetables, fruit or other things are placed inbaskets and the baskets are supported upon a projecting rim T whichpasses around in the inside of each retort at or above the water line.When evaporating syrup or other substances I use a vessel, W, set insideof the retort with a space for steam below and on all sides and at thetop it is made steam tight, preferably by means of a gasket M placed onthe upper edge of the retort and by the use of clamps 'Y the vessel issecured steam tight to the top of the retort. This leaves the suspendedvessel.

W open at the top to evaporate its contents which is facilitated by thepressure of steam on its bottom and sides.

R represents the smoke stack of the furnace. In each of the retorts Smay be placed or suspended a kettle, basket or other receptacle for thefruit or vegetables'to be cooked or evaporated as above described. Forthe purpose of increasing heat in each of the retorts I have placedpipes E below each of the retorts which extend down into the furnace,circulating the water of the retorts through the pipes and the pipesbeing in the furnace giving it great steam producing power forincreasing the steam in the retorts and by means of the safety valve Lany explosion is prevented. By my construction either of the retorts maybe shut off from the others and from the water tanks when desired ,andconnected with the cold water tank for cooling down the retorts whendesired to be opened. By this means I can have several retorts and openeither one of them for changing its contents at any time and disconnectfrom all the others and as soon as the change is made of the contents itcan be again connected with the others ready for another process, and byopening steam valves the steam is immediately equalized.

The pipe P which extends from the retorts to the water tanks is providedwith cutoff valves 0 sothat the steam can be put into tank Q at thetopthrough the ipe P for heating the Water in tank Q an hot water can betaken frojn said tank into either of the retorts.

In operation the fruit to be evaporated or cooked is placed in theretorts S, S and S The wateris heated by the furnace and the steamtherefrom passes around the receptacle to heat and cook the contentsthereof. After the fruit has been properly cooked one of the retorts iscut off from the others and cold Water is admitted thereto to cool thecontents of the receptacle. The top is then removed and the fruit isremoved from the retort without in any Wa interfering with the cookingof the frult in t e other retorts.

Havingthus described m invention what I claim as new and desire tosecure by Letters Patent of the United States is: v

In a cooking device, the combination with a plurality of retorts of acommon steam pipe connecting all of said retorts, valves in said pipefor cutting 0H each of said retorts from the others, a common cold watersupply pipe leading to each of said retorts, valves in said last namedpipe for controlling the passage of water to each of said retortsindependently of the others, a receptacle located within each of theretorts and spaced therefrom to permit the passage of-stea n or watertherearound a cover for said re e tacle, a plurality of handles for saidreceptac e adapted tooverlie the cover, and a set screw and lever ;saidlever being adapted to be screwed down upon said handles to thereby locksaid cover in position.

In testimony whereof I aflix my signature, in presence of two.subscribing witnesses.
